The GTK+ example you are running uses deprecated GTK+ function that
rely on GDK fonts (which are essentially X fonts). The linux-fb backend
tries to emulate this. Your problem could be related to the following
two lines from gdkfont-fb.c which don't look correct to me:

  lang = pango_context_get_lang (context);
  pango_font_get_metrics (pango_font, "fr", &metrics);

Not only does it use a hardcoded language, it also leaks the result
from pango_context_get_lang().


Salut, Sven
